Hairspray is a 2007 musical film produced by Zadan/Meron Productions and distributed by New Line Cinema. It was released in the United States, Canada, and the United Kingdom on July 20, 2007. The film is an adaptation of the Tony Award-winning 2002 Broadway musical of the same name, and a remake of John Waters' 1988 comedy film of the same name. Set in 1962 Baltimore, Maryland, the film follows a "pleasantly plump" teenager named Tracy Turnblad as she simultaneously pursues stardom as a dancer on a local TV show and rallies against racial segregation.

Adapted from both Waters's 1988 script and Thomas Meehan and Mark O'Donnell's book for the stage musical by screenwriter Leslie Dixon, the 2007 film version of Hairspray is directed and choreographed by Adam Shankman. Hairspray stars John Travolta, Michelle Pfeiffer, Christopher Walken, Amanda Bynes, James Marsden, Queen Latifah, Brittany Snow, Zac Efron, Elijah Kelley, Allison Janney, and introduces newcomer Nikki Blonsky as Tracy Turnblad. Hairspray features songs from the Broadway musical written by Marc Shaiman and Scott Wittman, as well as four new Shaiman/Wittman compositions not present in the original Broadway version.

Opening to mostly positive reviews, Hairspray met with financial success, breaking the record for biggest sales at opening weekend for a movie musical, which the film held until July 2008 when it was surpassed by Mamma Mia!. Hairspray went on to become the fourth highest grossing musical film in U.S. cinema history, behind the film adaptations of Grease, Chicago, and Mamma Mia!. Available in a variety of formats, Hairspray's Region 1 home video release took place on November 20, 2007. The USA Network has purchased the broadcast rights to Hairspray and is scheduled to debut the film on cable television in February 2010.

Adam Shankman and John Waters are currently working on a sequel to the film.
